A sudden twist of fate occurred and VOILA! he is walking towards me from the Customer Service desk. My mind raced. I didn't knew what I would do. But he smiled and held out a wave. I instinctively did the same thing. He pointed to my right and it seems he has a companion, I nodded and we cross paths.
AWKWARD. There's no more word to describe it. He is my estranged friend after all.
